NJU6052
White LED Driver with Automatic Dimming Control
!
GENERAL DESCRIPTION
The
NJU6052
is a white LED driver with an automatic
dimming control. It contains an output driver, a PWM
controller, a luminance sensor control (power supply for
sensor & A/D converter), a step-up DC/DC converter, a serial
interface, etc.
The output driver ensures a 60mA maximum capability
which allows the connection of 12 white LEDs (4 series x 3
parallels). Depending on the ambient light sensed with an
external luminance sensor, the PWM controller controls
PWM duty in 8 steps preselected out of 64 steps. In addition,
the frequency of the DC/DC converter is high so that it
permits the use of small, low-profile inductors and capacitors
to minimize the footprint in space-conscious applications.
All of these benefits make the
NJU6052
suitable for the
battery-powered portable applications such as a cellular
phone, a camcorder, PDA, etc.
